Hello Does anyone know of a source (or alternatively, a method) for finding the volatility estimates, both pre- and post IPO, for companies who went public in 2006/7? This is for some research on volatility estimates used by private companies for the purpose of option valuation. I believe that Bloomberg could help with this, but we don't have this source currently available, so if any business libraries out there have suggestions, they'd be gratefully received. Anyone interested in any responses I get, am happy to pass the information on.
